Help with power door lock actuator

I have a 2014 DC Offroad. The dealer with the warranty change the passenger front door actuator. Now i have the driver front door and the driver back door going bad. How can I fix then not going broke. The dealership wants 265 dollars for each actuator without installing them.

 

the lil motors in them wear out n go bad. I bought a 2 pack of the motors on ebay for 6 bucks and did the work myself to fix the actuator (and lube them up with some super lube while i was in there). Bout 2 hrs of my time and a few beers going slow.

You need a motor with a 20mm shaft that has been keyd ("flat shaft").

I bought the wrong ones (20mm shaft that wasnt keyed) used a dremel to put a flat spot on the shaft so the worm gear would slide on properly and never had an issue. The motor did spin in reverse but that was an easy fix just swapping the pins on the harness side.

 

ok thanks for the info
